Abstract

The Dufour and Soret effects on the two dimensional MHD steady flow of electrically conducting viscous fluid bounded by infinite sheets were examined. An incompressible viscous fluid filled the porous space. Mathematical analysis was performed in the presence of viscous dissipation, Joule heating and first order chemical reaction. By means of suitable transformations, the governing partial differential equations through momentum, energy and concentration laws were transformed into the ordinary differential equations. The resulting equations were solved by homotopy analysis method (HAM). Convergence of the series solutions was ensured. The effects of emerging parameters on the dimensionless velocities, temperature and concentration fields were analyzed. Skin friction coefficient, Nusselt number and Sherwood number were also analyzed.
